Encryption, when unblock etc. needs the action that identification of fingerprint instructs, fingerprint shadow is started at handheld apparatus
As, after reading via fingerprint sensing device, can first deliver to image working area, if within the setting time,
Fingerprint working area only obtains the picture number preset, and that represents user and is doing the dynamic of identification of fingerprint
Make；If within the setting time, fingerprint working area obtains more than the picture number preset or displacement
Have a greater change, then image comparing unit will be transferred to do velocity estimated, transfer to mobile the most again
Vector processing unit does motion-vector and judges, and then draws a motion-vector output.By this, hands
Machine system can obtain may make up the data of numeral, word or gesture instruction.
In the software of registered fingerprint, the common factor whether increasing numeral, word or gesture can be set
Judge, and according to the mode of fingerprint register and the mode of the numeral of setting, word or gesture,
User presses or mobile, to complete fingerprint register or numeral, word or hands on fingerprint sensing device
